CASE STUDY 2
ARTIFICIAL LIFT FAILURE PREDICTION
European Operator - France
SonicAnalyst™ Downhole Event Monitor
Monitor a PCP for indications of when the artificial lift system would fail.
The graph presents averaged noise amplitude data together with the max and min torque readings observed at surface during a few minutes every hour. Data gathered by the SonicAnalyst™ Monitor correlated with rod string torque and four distinct noise / torque peaks were observed before the rod string broke.
Characteristic noise graphs for each type of artificial lift system can be gathered over time and when correlated with surface observations such as torque can provide a useful predictive and preventative warning to operators allowing AL units to be shut-down and worked over prior to failure, avoiding expensive fishing jobs.
